24-15=9 m/s slower in 12 seconds. So 9/12 m/s² slower. Therefore the acceleration is -0,75 m/s²

Kenetic energy increasing because velocity increased
Ymorist [56]

Answer:

Explanation:

The formula for kinetic energy  Ke=1/2mv^2 where Ke is kinetic energy, m=mass, and v= velocity.

If the kinetic energy is increased that means that there must be an increase in mass or velocity. However, since the velocity is squared that means that velocity affects the kinetic energy of the object more than the mass does.

The statement that no two electrons in the same atom can have the same four quantum numbers is a restatement of
andreev551 [17]

Answer:

Pauli exclusion principle

Explanation:

Pauli's exclusion principle speaks to the quantum numbers assigned to an electron to describe it's general position and movement. Two electrons can occupy the same energy level (which is described by the first quantum number-the principal quantum number), the orbital angular momentum quantum number (represented by the second number) and magnetic quantum number. electrons that have the same value for all three numbers will have different spins. one will have positive a half while the other has negative a half. Therefore they will never have the same complement of quantum numbers

what do i wright: You are a drop of water going through the water cycle. Where do you go? How do you get there? What processes d
kenny6666 [7]

Explanation:

As the Sun heats the ocean, the water evaporates, turning into a gas. Sometimes this gas meets cooler air, and the gas changes into drops of water. This process is called condensation. Drops of water fall back down to Earth again as precipitation, which can be in the form of rain, snow, sleet, or hail

three phases of water cycle are

evaporation, condensation, <em>precipitation</em>

2. A sailor pushes a 100.0 kg crate up a ramp that is 3.00 m high and 5.00 m long onto the deck of a ship. He
Scrat [10]

Answer:

Mechanical advantage of the ramp = \frac{980}{650} = 1.51

Efficiency of the ramp = \frac{Actual\hspace{0.1cm} work\hspace{0.1cm} done}{Work} = \frac{100\times 9.8\times 3}{650\times 5} = \frac{2940}{3250} = 0.9046 = 90.46%

Explanation:

i) Mechanical advantage of the ramp = \frac{980}{650} = 1.51

ii) Efficiency of the ramp = \frac{Actual\hspace{0.1cm} work\hspace{0.1cm} done}{Work} = \frac{100\times 9.8\times 3}{650\times 5} = \frac{2940}{3250} = 0.9046 = 90.46%
